Biography
Casimir was born 15 July 1909.
From 1932 to mid-1933, Casimir worked as an assistant to Wolfgang Pauli at ETH Zurich. During this period, he worked on the relativistic theory of the electron, in particular, evaluating deviations of the Klein-Nishina equation in the case of bound electrons. To attack the problem, he invented a number of mathematical tools. One in particular is still referred to as the “Casimir Trick": in particle interaction calculations, it is a familiar procedure of trace formation and projections using products of Dirac matrices.
In 1938, Casimir became a physics professor at
In 1942, during World War II, Casimir moved to the Philips Natuurkundig Laboratorium (Philips Physics Laboratory, NatLab) in Eindhoven, the Netherlands.[8] He remained an active scientist and in 1945 wrote a well-known paper on Lars Onsager's principle of microscopic reversibility. He became a co-director of Philips NatLab in 1946 and a member of the board of directors of the company in 1956.[9] He retired from Philips in 1972.[10]
Although he spent much of his professional life in industry, Hendrik Casimir was one of the great Dutch theoretical physicists. Casimir made many contributions to science during his years in research from 1931 to 1950. These contributions include: pure mathematics,
While at
He was awarded six honorary doctor degrees by universities outside the Netherlands. He received numerous awards and prizes, among them the illustrious IRI Medal from the Industrial Research Institute in 1976. He was a Foreign Associate of the National Academy of Engineering. In 1982, he was awarded the Wilhelm Exner Medal.[12] He was an elected member of the American Academy of Arts and Sciences, the United States National Academy of Sciences, and the American Philosophical Society.[13][14][15]
